Installation guidelines:
Maintain 0.5–1.5mm alignment tolerance during mounting.
For vertical installations exceeding 300mm stroke,
use external guide mechanisms to prevent piston rod deflection.
Relubricate every 500km of cumulative travel distance.
Critical note: Avoid side load exceeding 15N.
When stroke exceeds 400mm, reduce maximum operating pressure
by 20% to prevent buckling. Not recommended for vacuum applications.
